AUTOMATIC LIQUID CONTROL.

Application filed March 6, 1923. Serial No. 623,207.

To all whom it may concern: I

Be it known that I, EDWIN E. J OSLIN, a citizen of the United States,residing at 469 Salmon Street, in the city of Portland, in the county ofMultnoinah and the State of Oregon, have invented a new and usefulImprovement in Automatic Liquid Gontrols, of which the following is aspecification. I r 1 My invention is intended for, use in apartmenthouses, residences, hotels, factories and all places where water isbeing drawn for personal or other uses and where. it is necessary tomaintain a supply on hand in advance of the use of -thesame,'thiscondition exists in so many places in modern life andso much troubleis'had with existing devices that I set out some time ago to devisemeans that would accomplish the result and at the sametime lessen thetroubles incident to the use of thepresent devices and at the same timeto lessen the cost of installation of the same as a first cost.

For a more complete. description of my invention reference ismade to theaccompanying drawings in which Fig.1 is a side elevation of a controlbox, into which the water is admitted from the source of supply and fromwhere it is distributed to the variousother points of use, it is assumedfor the purpose of this description that the same is to be used in astructure wherein water is being distributed to various compartmentsonthe same level, on certain floors, and that the operating conditionswill be the same, but it is assumed that I do not wish to' belimited inthe patent protectionto be asked for and to be granted that I am to belimited to the sam in itsapplication for use on water; as any liquid maybe regulated and controlled by thisdevice. The side ofthecontainer asshown in Fig. 1 is partially broken away to better illustrate the innerconstruction of the same and to show the method of journaling andcontrolling my siphon arrangement that I have utilized in the op eratingof the same. Fig. 2 is a side elevation of the control box, also, butillustrates the same from the opposite side from that shown in Fig. 1and shows'the float controls and howthe same regulate the level oftheliquid to be controlled. Fig. 3 is a top plan view of the same, but:shows the transverse partition that separates-the container intotwoseparate and. distinct will, be explained more in detail. crook ofsaid goose-neck a hollow ball-float .15 isrigidly secured, as by clip16. Secured compartments one for the retention of'the liquid until thesame should be required for use, and the other to be used as a containerthrough which the liquid is to pass to the place of ultimate use. v

Fig. 4 is an inverted plan viewof an ad justable control valvethat maybeplaced in the bottom of a drip-oupmounted upon the float, control'ofamaster tank.

Referring to said views, wherein similar characters of,referenceindicate like parts throughout the same, the reference numeral1v designates a mast er control tank of my invention, preferably ofrectangular configuration and-.divided into receiving. and dischargecompartments 2 and 3, respectively, by the vertical partition 5, Thereceivingcompartment2 is of relativel large capacity and is suppliedwith water t rough an inletpipe 6 communicating with a source of watersupply under pressure. WVater is admitted from said inlet pipe. andcontrolled by a valve7 of any well known type as used in flush-tanksadapted, to be opened ,,and closed in accordance with the level ofwat'erin the compartment 2 by the float 8. A tubular yoke 10is j ournaled forvpartial .rotation in the side walls of saidfta nk and in said partition.Said yoke extends at one end through oneofsaid side walls and isprovided at the outside with a lever 11 through which it may oscillated.I In said compartment 2 said yoke is provided with a short branch pipe12 having an. upturned goose-neck 13 at its opposlte open end.

aidopen end desirably projects slightly above thewater when in elevated.position but owingto-said goose-neck. a w'ater'seal is maintainedthrough which asiphonic elfect isobtained whenthe pipe end is lowered,as In, the

near ,the extremity of said goose-neck is a bracket 17 extendinghorizontally when the pipe 12 is raised in its uppermost position, asindicated in full lines in Fig. 2, and is provided with a circular boss18 at its outer end affording a socket for a vverticallydisposedcylindrical cup 20. 'Drip-openings21 to drainsaidcup are provided insaid socket, which; openings may be adjusted to: a predetermined extentof. opening by means of aperforated plate. 22 secured by a central screw23. i

'25 indicatesa short, branch pipecommuleg of nicatively connected tosaid; yoke and dis.- posed-w-ithin the discharge compartment 3. Saidpipe is similar to the pipe 12, being provided with a correspondingupturned goose-neck 26, and constitutes the discharge an inverted siphonwhich is operable when said goose-neck ends are depressed to draw waterinto the receiving end: 12. 27 designates an outlet for the discharge ofwater from the compartment 3;

The operation of the invention may be described as follows: \Vith thecontrol tank apparatus in its normal quiescent condition, as indicatedin full lines in Figs. 1 to 8, inclusive, the receiving compartment 2 isfull ofwater to near the top of the partition while the compartment 3isempty. Upon the operating of the lever 11 the yoke 10' is oscillatedto'lower said pipes 12 and 25 and submerge the open end of the formerwhereby a siphonic eiiect is produced causing the water to flow from thecompartment 2 to the compartment 3 through the pipe 12, the tubular yoke10, and the pipe 25. The ballfioat 15 is submergedwitli said goose-neck13 and has a tendency to lift the pipe 12 to the top of the water butsuch action is resisted by the gravity of the water contained in the cup20'which is filled with water as the pipe 12 is lowered, as indicated inbroken lines in Fig. 2, and as the water contained in compartment 2recedes tends to depress said pipe in opposition to the buoyancy of thefloat until the regulated leakage from said cup through apertures 21;allows the float to raise the goose-neck 13 above the level of the waterand to its original position.

' Water flowing from the receiving compartment passes through pipe 25into the discharge compartment and thence through the discharge outlet27'.
